Abstract

The invention discloses a low-noise cooling system sawtooth centrifugal impeller test design testing device and method, sawtooth blades with different parameters and a centrifugal impeller are connected through bolts, the low-noise cooling system of the sawtooth blades with different parameters is subjected to noise testing, the parameters of the sawtooth blades and corresponding test data are subjected to normalization processing, and the test result is obtained. Reasonable blade sawtooth structure parameters are matched and optimized to be used in noise reduction design of a low-noise cooling system, and the efficient sawtooth centrifugal impeller test design testing device and method are achieved. The method has the advantages that the development time is remarkably shortened, the development cost is reduced, and the design quality is improved; the parameter design problem of the sawtooth bionic blade is solved, noise of a low-noise cooling system product is effectively controlled, and the comfort and environment friendliness of a rail train are improved. Aerodynamic noise simulation does not need to be carried out on the low-noise cooling system, and the problems of long calculation period, high calculation resource requirements and the like are solved.

Description

technical field [0001] The invention relates to the technical field of ventilation and cooling, in particular to a device and method for experimental design and testing of a sawtooth centrifugal impeller of a low-noise cooling system. Background technique [0002] Centrifugal impellers are widely used in rail vehicle ventilation and cooling systems and other rotating machinery, and are also key components of aerodynamic noise. To reduce the aerodynamic noise of the ventilation and cooling system of rail vehicles, the impeller structure design is one of the key technologies for noise reduction. [0003] The cooling system is a heat dissipation component used for electronic components such as converters, transformers and traction motors of rail trains. It is one of the key core components of rail trains. There are many mechanical and electrical modules inside, such as fans and radiators, racks, Motors, pumps, contactors, water pipes, busbars and wires, etc. All kinds of comp...
